BACKGROUND

All publications cited in this application are herein incorporated byreference.

There are numerous steps in the development of any novel, desirableplant germplasm. Plant breeding begins with the analysis and definitionof problems and weaknesses of the current germplasm, the establishmentof program goals, and the definition of specific breeding objectives.The next step is selection of germplasm that possesses the traits tomeet the program goals. The goal is to combine in a single variety animproved combination of desirable traits from the parental germplasm.These important traits may include higher seed yield, resistance todiseases and insects, better stems and roots, tolerance to drought andheat, and better agronomic quality.

Soybean, Glycine max (L.) Merr., is an important and valuable fieldcrop. Thus, a continuing goal of soybean plant breeders is to developstable, high yielding soybean cultivars that are agronomically sound.The reasons for this goal are to maximize the amount of grain producedon the land used and to supply food for both animals and humans. Toaccomplish this goal, the soybean breeder must select and developsoybean plants that have traits that result in superior cultivars.

The foregoing examples of the related art and limitations relatedtherewith are intended to be illustrative and not exclusive. Otherlimitations of the related art will become apparent to those of skill inthe art upon a reading of the specification.

F₃. The “F₃” symbol denotes a generation resulting from the selfing ofthe F₂ generation along with selection for type and rogueing ofoff-types. The “F” number is a term commonly used in genetics, anddesignates the number of the filial generation. The “F₃” generationdenotes the offspring resulting from the selfing or self mating ofmembers of the generation having the next lower “F” number, that is, the“F₂” generation.

Gene. Gene refers to a segment of nucleic acid. A gene can be introducedinto a genome of a species, whether from a different species or from thesame species, using transformation, gene editing techniques, or variousbreeding methods.

Hilum. Hilum refers to the scar left on the seed that marks the placewhere the seed was attached to the pod prior to the seed beingharvested.

Hypocotyl. A hypocotyl is the portion of an embryo or seedling betweenthe cotyledons and the root. Therefore, it can be considered atransition zone between shoot and root.

Iron Deficiency Chlorosis. Iron deficiency chlorosis (IDC) is ayellowing of the leaves caused by a lack of iron in the soybean plant.Iron is essential in the formation of chlorophyll, which gives plantstheir green color. In high pH soils iron becomes insoluble and cannot beabsorbed by plant roots. Soybean cultivars differ in their geneticability to utilize the available iron. A score of 9 means no stunting ofthe plants or yellowing of the leaves and a score of 1 indicates theplants are dead or dying caused by iron deficiency, a score of 5 meansplants have intermediate health with some leaf yellowing.

Linoleic Acid Percent. Linoleic acid is one of the five most abundantfatty acids in soybean seeds. It is measured by gas chromatography.

Locus. A locus confers one or more traits such as, for example, malesterility, herbicide tolerance, insect resistance, disease resistance,waxy starch, modified fatty acid metabolism, modified phytic acidmetabolism, modified carbohydrate metabolism, and modified proteinmetabolism. The trait may be, for example, conferred by a naturallyoccurring gene introduced into the genome of the variety by geneediting, backcrossing, a natural or induced mutation, or a transgeneintroduced through genetic transformation techniques. A locus maycomprise one or more alleles integrated at a single chromosomallocation.

Lodging Resistance. Lodging resistance refers to the relative presenceof the plant lying on or toward the ground and is on a 1 to 5 scoringbasis. A lodging score of 5 would indicate the plant is basically lyingon the ground. A score of 1 indicates that most or all the plants in arow are standing prostrate.

Maturity Date. Plants are considered mature when 95% of the pods havereached their mature color. The number of days are calculated eitherfrom August 31 or from the planting date.

Maturity Group. Maturity group refers to an agreed-on industry divisionof groups of varieties based on zones in which they are adapted,primarily according to day length or latitude. They consist of very longday length varieties (Groups 000, 00, 0), and extend to very short-daylength varieties (Groups VII, VIII, IX, X).

Oil or Oil Percent. Soybean seeds contain a considerable amount of oil.Oil is measured by NIR spectrophotometry and is reported as a percentagebasis.

Oleic Acid Percent. Oleic acid is one of the five most abundant fattyacids in soybean seeds and is measured by gas chromatography and isreported as a percent of the total oil content.

Palmitic Acid Percent. Palmitic acid is one of the five most abundantfatty acids in soybean seeds and is measured by gas chromatography andis reported as a percent of the total oil content.

Phytophthora Tolerance. Tolerance to Phytophthora root rot is rated on ascale of 1 to 9, with a score of 9 being the best or highest toleranceranging down to a score of 1 which indicates the plants have notolerance to Phytophthora.

Plant. A plant refers to a whole plant, any part thereof, or a cell ortissue culture derived from a plant, comprising any of: whole plants,plant components or organs (e.g., leaves, stems, roots, etc.), planttissues, seeds, embryos, plant cells, protoplasts and/or progeny of thesame. A plant cell is a biological cell of a plant, taken from a plantor derived through culture of a cell taken from a plant.

The number preceding the decimalpoint in the RM refers to the maturity group. The number following thedecimal point refers to the relative earliness or lateness within eachmaturity group. For example, a 3.0 is an early group III variety, whilea 3.9 is a late group III variety.

Seed Yield (Bushels/Acre). The yield in bushels/acre is the actual yieldof the grain at harvest.

Seeds Per Pound. Soybean seeds vary in seed size; therefore, the numberof seeds required to make up one pound also varies. The number of seedsper pound affects the pounds of seed required to plant a given area andcan also impact end uses.

Single Gene Converted (Conversion). Single gene converted (conversion)plants refers to plants which are developed by a plant breedingtechnique called backcrossing wherein essentially all of the desiredmorphological and physiological characteristics of a variety arerecovered in addition to the single gene transferred into the varietyvia the backcrossing technique or via genetic engineering. Byessentially all of the morphological and physiological characteristics,it is meant that the characteristics of a plant are recovered that areotherwise present when compared in the same environment, other than anoccasional variant trait that might arise during backcrossing or directintroduction of a transgene.

Sulfonylurea Reaction. Sulfonylurea reaction refers to a plant'stolerance, resistance or susceptibility to sulfonylurea herbicides andrefers to a plant which contains the ALS gene, which confers resistanceto some of the sulfonylurea herbicides.

The complexity of inheritance influences choice of the breeding method.Backcross breeding is used to transfer one or a few favorable genes fora highly heritable trait into a desirable cultivar. This approach hasbeen used extensively for breeding disease-resistant cultivars. Variousrecurrent selection techniques are used to improve quantitativelyinherited traits controlled by numerous genes. The use of recurrentselection in self-pollinating crops depends on the ease of pollination,the frequency of successful hybrids from each pollination, and thenumber of hybrid offspring from each successful cross.

Promising advanced breeding lines are thoroughly tested and compared toappropriate standards in environments representative of the commercialtarget area(s) for three or more years. The best lines are candidatesfor new commercial cultivars; those still deficient in a few traits maybe used as parents to produce new populations for further selection.

A population means a set comprising any number, including one, ofindividuals, objects, or data from which samples are taken forevaluation, e.g. estimating QTL effects and/or disease tolerance. Mostcommonly, the terms relate to a breeding population of plants from whichmembers are selected and crossed to produce progeny in a breedingprogram. A population of plants can include the progeny of a singlebreeding cross or a plurality of breeding crosses and can be eitheractual plants or plant derived material, or in silico representations ofplants. The member of a population need not be identical to thepopulation members selected for use in subsequent cycles of analyses nordoes it need to be identical to those population members ultimatelyselected to obtain a final progeny of plants. Often, a plant populationis derived from a single biparental cross but can also derive from twoor more crosses between the same or different parents. Although apopulation of plants can comprise any number of individuals, those ofskill in the art will recognize that plant breeders commonly usepopulation sizes ranging from one or two hundred individuals to severalthousand, and that the highest performing 5% to 20% of a population iswhat is commonly selected to be used in subsequent crosses in order toimprove the performance of subsequent generations of the population in aplant breeding program.

These processes, which lead to the final step of marketing anddistribution, usually take from eight to twelve years from the time thefirst cross is made. Therefore, development of new cultivars is atime-consuming process that requires precise forward planning, efficientuse of resources, and a minimum of changes in direction.

A most difficult task is the identification of individuals that aregenetically superior, because for most traits the true genotypic valueis masked by other confounding plant traits or environmental factors.One method of identifying a superior plant is to observe its performancerelative to other experimental plants and to a widely grown standardcultivar. If a single observation is inconclusive, replicatedobservations provide a better estimate of its genetic worth.

The goal of soybean plant breeding is to develop new and superiorsoybean cultivars and hybrids. The breeder initially selects and crossestwo or more parental lines, followed by repeated selfing and selection,producing many new genetic combinations. The breeder can theoreticallygenerate billions of different genetic combinations via crossing,selection, selfing and mutations. Therefore, a breeder will neverdevelop the same line, or even very similar lines, having the samesoybean traits from the exact same parents.

Each year, the plant breeder selects the germplasm to advance to thenext generation. This germplasm is grown under different geographicalclimate and soil conditions and further selections are then made duringand at the end of the growing season. The cultivars that are developedare unpredictable because the breeder's selection occurs in environmentswith no control at the DNA level, and with millions of differentpossible genetic combinations being generated. A breeder of ordinaryskill in the art cannot predict the final resulting lines he develops,except possibly in a very gross and general fashion. The same breedercannot produce the same cultivar twice by using the same originalparents and the same selection techniques. This unpredictability resultsin the expenditure of large amounts of research monies to developsuperior new soybean cultivars.

The development of new soybean cultivars requires the development andselection of soybean varieties, the crossing of these varieties andselection of superior hybrid crosses. The hybrid seed is produced bymanual crosses between selected male-fertile parents or by using malesterility systems. These hybrids are selected for certain single genetraits such as pod color, flower color, pubescence color or herbicideresistance which indicate that the seed is truly a hybrid. Additionaldata on parental lines, as well as the phenotype of the hybrid,influence the breeder's decision whether to continue with the specifichybrid cross.

Breeding programs combine desirable traits from two or more cultivars orvarious broad-based sources into breeding pools from which cultivars aredeveloped by selfing and selection of desired phenotypes. Pedigreebreeding is used commonly for the improvement of self-pollinating crops.Two parents that possess favorable, complementary traits are crossed toproduce an F₁. An F₂ population is produced by selfing one or severalFis. Selection of the best individuals may begin in the F₂ population;then, beginning in the F₃, the best individuals in the best families areselected. Replicated testing of families can begin in the F₄ generationto improve the effectiveness of selection for traits with lowheritability. At an advanced stage of inbreeding (i.e., F₆ and F₇), thebest lines or mixtures of phenotypically similar lines are tested forpotential release as new cultivars.

As used herein, “fertilization” and/or “crossing” broadly includesbringing the genomes of gametes together to form zygotes but alsobroadly may include pollination, syngamy, fecundation and otherprocesses related to sexual reproduction. Typically, a cross and/orfertilization occurs after pollen is transferred from one flower toanother, but those of ordinary skill in the art will understand thatplant breeders can leverage their understanding of fertilization and theoverlapping steps of crossing, pollination, syngamy, and fecundation tocircumvent certain steps of the plant life cycle and yet achieveequivalent outcomes, for example, a plant or cell of a soybean cultivardescribed herein. In certain embodiments, a user of this innovation cangenerate a plant of the claimed invention by removing a genome from itshost gamete cell before syngamy and inserting it into the nucleus ofanother cell. While this variation avoids the unnecessary steps ofpollination and syngamy and produces a cell that may not satisfy certaindefinitions of a zygote, the process falls within the definition offertilization and/or crossing as used herein when performed inconjunction with these teachings. In certain embodiments, the gametesare not different cell types (i.e. egg vs. sperm), but rather the sametype and techniques are used to effect the combination of their genomesinto a regenerable cell. Other embodiments of fertilization and/orcrossing include circumstances where the gametes originate from the sameparent plant, i.e. a “self” or “self-fertilization”. While selfing aplant does not require the transfer pollen from one plant to another,those of skill in the art will recognize that it nevertheless serves asan example of a cross, just as it serves as a type of fertilization.Thus, methods and compositions taught herein are not limited to certaintechniques or steps that must be performed to create a plant or anoffspring plant of the claimed invention, but rather include broadly anymethod that is substantially the same and/or results in compositions ofthe claimed invention.

Crop Performance

Crop performance is used synonymously with plant performance and refersto of how well a plant grows under a set of environmental conditions andcultivation practices. Crop performance can be measured by any metric auser associates with a crop's productivity (e.g. yield), appearanceand/or robustness (e.g. color, morphology, height, biomass, maturationrate), product quality (e.g., seed protein content, seed oil content,seed carbohydrate content, etc.), cost of goods sold (e.g. the cost ofcreating a seed, plant, or plant product in a commercial, research, orindustrial setting) and/or a plant's tolerance to disease (e.g. aresponse associated with deliberate or spontaneous infection by apathogen), pests, microbes, fungi, and/or environmental stress (e.g.drought, flooding, low nitrogen or other soil nutrients, wind, hail,temperature, day length, etc.). Crop performance can also be measured bydetermining a crop's commercial value and/or by determining thelikelihood that a particular inbred, hybrid, or variety will become acommercial product, and/or by determining the likelihood that theoffspring of an inbred, hybrid, or variety will become a commercialproduct. Crop performance can be a quantity (e.g. the volume or weightof seed or other plant product measured in liters or grams) or someother metric assigned to some aspect of a plant that can be representedon a scale (i.e., assigning a 1 to10 value to a plant based on itsdisease tolerance).

A microbe will be understood to be a microorganism, i.e. a microscopicorganism, which can be single celled or multicellular. Microorganismsare very diverse and include all the bacteria, archaea, protozoa, fungi,and algae, especially cells of plant pathogens and/or plant symbionts.Certain animals are also considered microbes, e.g. rotifers. In variousembodiments, a microbe can be any of several different microscopicstages of a plant or animal. Microbes also include viruses, viroids, andprions, especially those which are pathogens or symbionts to cropplants.

A fungus includes any cell or tissue derived from a fungus, for examplewhole fungus, fungus components, organs, spores, hyphae, mycelium,and/or progeny of the same. A fungus cell is a biological cell of afungus, taken from a fungus or derived through culture of a cell takenfrom a fungus.

A pest is any organism that can affect the performance of a plant in anundesirable way. Common pests include microbes, animals (e.g. insectsand other herbivores), and/or plants (e.g. weeds). Thus, a pesticide isany substance that reduces the survivability and/or reproduction of apest, e.g. fungicides, bactericides, insecticides, herbicides, and othertoxins.

Tolerance or improved tolerance in a plant to disease conditions (e.g.growing in the presence of a pest) will be understood to mean anindication that the plant is less affected by the presence of pestsand/or disease conditions with respect to yield, survivability and/orother relevant agronomic measures, compared to a less tolerant, more“susceptible” plant. Tolerance is a relative term, indicating that a“tolerant” plant survives and/or performs better in the presence ofpests and/or disease conditions compared to other (less tolerant) plants(e.g., a different soybean cultivar) grown in similar circumstances. Asused in the art, tolerance is sometimes used interchangeably with“resistance”, although resistance is sometimes used to indicate that aplant appears maximally tolerant to, or unaffected by, the presence ofdisease conditions. Plant breeders of ordinary skill in the art willappreciate that plant tolerance levels vary widely, often representing aspectrum of more-tolerant or less-tolerant phenotypes, and are thustrained to determine the relative tolerance of different plants, plantlines or plant families and recognize the phenotypic gradations oftolerance.

Desired Trait or Traits

In certain embodiments, plants disclosed herein can be modified toexhibit at least one desired trait, and/or combinations thereof. Theembodiments disclosed herein, are not limited to any set of traits thatcan be considered desirable, but nonlimiting examples include malesterility, herbicide tolerance, pest tolerance, disease tolerance,modified fatty acid metabolism, modified carbohydrate metabolism,modified seed yield, modified seed oil, modified seed protein, modifiedlodging resistance, modified shattering, modified iron-deficiencychlorosis, modified water use efficiency, and/or combinations thereof.Desired traits can also include traits that are deleterious to plantperformance, for example, when a researcher desires that a plantexhibits such a trait in order to study its effects on plantperformance.

Methods disclosed herein include conferring desired traits to plants,for example, by mutating sequences of a plant, introducing nucleic acidsinto plants, using plant breeding techniques and various crossingschemes, etc. These methods are not limited as to certain mechanisms ofhow the plant exhibits and/or expresses the desired trait. In certainnonlimiting embodiments, the trait is conferred to the plant byintroducing a nucleotide sequence (e.g. using plant transformationmethods) that encodes production of a certain protein by the plant. Incertain nonlimiting embodiments, the desired trait is conferred to aplant by causing a null mutation in the plant's genome (e.g. when thedesired trait is reduced expression or no expression of a certaintrait). In certain nonlimiting embodiments, the desired trait isconferred to a plant by crossing two plants to create offspring thatexpress the desired trait. It is expected that users of these teachingswill employ a broad range of techniques and mechanisms known to bringabout the expression of a desired trait in a plant. Thus, as usedherein, conferring a desired trait to a plant is meant to include anyprocess that causes a plant to exhibit a desired trait, regardless ofthe specific techniques employed.

Using Soybean Cultivar 2940889 to Develop Other Soybean Varieties

Soybean varieties such as soybean cultivar 2940889 are typicallydeveloped for use in seed and grain production. However, soybeanvarieties such as soybean cultivar 2940889 also provide a source ofbreeding material that may be used to develop new soybean varieties.Plant breeding techniques known in the art and used in a soybean plantbreeding program include, but are not limited to, recurrent selection,mass selection, bulk selection, mass selection, backcrossing, pedigreebreeding, open pollination breeding, restriction fragment lengthpolymorphism enhanced selection, genetic marker enhanced selection,making double haploids, and transformation. Often combinations of thesetechniques are used. The development of soybean varieties in a plantbreeding program requires, in general, the development and evaluation ofhomozygous varieties. There are many analytical methods available toevaluate a new variety. The oldest and most traditional method ofanalysis is the observation of phenotypic traits, but genotypic analysismay also be used.

Additional Breeding Methods

One embodiment is directed to methods for producing a soybean plant bycrossing a first parent soybean plant with a second parent soybeanplant, wherein the first or second soybean plant is the soybean plantfrom soybean cultivar 2940889. Further, both first and second parentsoybean plants may be from soybean cultivar 2940889. Therefore, anymethods using soybean cultivar 2940889 are part of the embodiments:selfing, backcrosses, hybrid breeding, and crosses to populations. Anyplants produced using soybean cultivar 2940889 as at least one parentare also within the scope of the embodiments. Any such methods usingsoybean variety 2940889 are part of the embodiments: selfing, sibbing,backcrosses, mass selection, pedigree breeding, bulk selection, hybridproduction, crosses to populations, and the like. These methods are wellknown in the art and some of the more commonly used breeding methods aredescribed herein. Descriptions of breeding methods can be found in oneof several reference books (e.g., Allard, Principles of Plant Breeding(1960); Simmonds, Principles of Crop Improvement (1979); Sneep, et al.(1979); Fehr, “Breeding Methods for Cultivar Development,” Chapter 7,Soybean Improvement, Production and Uses, 2^(nd) ed., Wilcox editor(1987)).

The following describes breeding methods that may be used with soybeancultivar 2940889 in the development of further soybean plants. One suchembodiment is a method for developing a cultivar 2940889 progeny soybeanplant in a soybean plant breeding program comprising: obtaining thesoybean plant, or a part thereof, of cultivar 2940889, utilizing saidplant, or plant part, as a source of breeding material, and selecting asoybean cultivar 2940889 progeny plant with molecular markers in commonwith cultivar 2940889 and/or with morphological and/or physiologicalcharacteristics selected from the characteristics listed in Tables 1and/or 2 and/or 3 and/or 4. Breeding steps that may be used in thesoybean plant breeding program include pedigree breeding, backcrossing,mutation breeding, and recurrent selection. In conjunction with thesesteps, techniques such as RFLP-enhanced selection, genetic markerenhanced selection (for example, SSR markers), and the making of doublehaploids may be utilized.

Another method involves producing a population of soybean cultivar2940889 progeny soybean plants, comprising crossing cultivar 2940889with another soybean plant, thereby producing a population of soybeanplants which, on average, derive 50% of their alleles from soybeancultivar 2940889. A plant of this population may be selected andrepeatedly selfed or sibbed with a soybean cultivar resulting from thesesuccessive filial generations. One embodiment is the soybean cultivarproduced by this method and that has obtained at least 50% of itsalleles from soybean cultivar 2940889.

One of ordinary skill in the art of plant breeding would know how toevaluate the traits of two plant varieties to determine if there is nosignificant difference between the two traits expressed by thosevarieties. For example, see, Fehr and Walt, Principles of CultivarDevelopment, pp. 261-286 (1987). Thus, embodiments include soybeancultivar 2940889 progeny soybean plants comprising a combination of atleast two cultivar 2940889 traits selected from the group consisting ofthose listed in Tables 1 and/or 2 and/or 3 and/or 4 or soybean cultivar2940889 combination of traits listed in the Summary, so that saidprogeny soybean plant is not significantly different for said traitsthan soybean cultivar 2940889 as determined at the 5% significance levelwhen grown in the same environmental conditions. Using techniquesdescribed herein, molecular markers may be used to identify said progenyplant as a soybean cultivar 2940889 progeny plant. Mean trait values maybe used to determine whether trait differences are significant, andpreferably the traits are measured on plants grown under the sameenvironmental conditions. Once such a variety is developed, its value issubstantial since it is important to advance the germplasm base as awhole in order to maintain or improve traits such as yield, diseaseresistance, pest resistance, and plant performance in extremeenvironmental conditions.

Progeny of soybean cultivar 2940889 may also be characterized throughtheir filial relationship with soybean cultivar 2940889, as for example,being within a certain number of breeding crosses of soybean cultivar2940889. A breeding cross is a cross made to introduce new genetics intothe progeny, and is distinguished from a cross, such as a self or a sibcross, made to select among existing genetic alleles. The lower thenumber of breeding crosses in the pedigree, the closer the relationshipbetween soybean cultivar 2940889 and its progeny. For example, progenyproduced by the methods described herein may be within 1, 2, 3, 4, or 5breeding crosses of soybean cultivar 2940889.

Pedigree Breeding

Pedigree breeding starts with the crossing of two genotypes, such assoybean cultivar 2940889 and another soybean variety having one or moredesirable characteristics that is lacking or which complements soybeancultivar 2940889. If the two original parents do not provide all thedesired characteristics, other sources can be included in the breedingpopulation. In the pedigree method, superior plants are selfed andselected in successive filial generations. In the succeeding filialgenerations, the heterozygous condition gives way to homogeneousvarieties as a result of self-pollination and selection. Typically, inthe pedigree method of breeding, five or more successive filialgenerations of selfing and selection is practiced: F₁ to F₂; F₂ to F₃;F₃ to F₄; F₄ to F₅; etc. After a sufficient amount of inbreeding,successive filial generations will serve to increase seed of thedeveloped variety. Preferably, the developed variety compriseshomozygous alleles at about 95% or more of its loci.

Backcross Breeding

Backcross breeding has been used to transfer genes for a simplyinherited, highly heritable trait into a desirable homozygous cultivaror inbred line which is the recurrent parent. The source of the trait tobe transferred is called the donor parent. After the initial cross,individuals possessing the phenotype of the donor parent are selectedand repeatedly crossed (backcrossed) to the recurrent parent. Theresulting plant is expected to have the attributes of the recurrentparent (e.g., cultivar) and the desirable trait transferred from thedonor parent.

In addition to being used to create a backcross conversion, backcrossingcan also be used in combination with pedigree breeding. As discussedpreviously, backcrossing can be used to transfer one or morespecifically desirable traits from one variety, the donor parent, to adeveloped variety called the recurrent parent, which has overall goodagronomic characteristics yet lacks that desirable trait or traits.However, the same procedure can be used to move the progeny toward thegenotype of the recurrent parent, but at the same time retain manycomponents of the nonrecurrent parent by stopping the backcrossing at anearly stage and proceeding with selfing and selection. For example, asoybean variety may be crossed with another variety to produce afirst-generation progeny plant. The first-generation progeny plant maythen be backcrossed to one of its parent varieties to create a BC₁ orBC₂. Progeny are selfed and selected so that the newly developed varietyhas many of the attributes of the recurrent parent and yet several ofthe desired attributes of the nonrecurrent parent. This approachleverages the value and strengths of the recurrent parent for use in newsoybean varieties.

Therefore, an embodiment is a method of making a backcross conversion ofsoybean variety 2940889, comprising the steps of crossing a plant ofsoybean variety 2940889 with a donor plant comprising a desired trait,selecting an F₁ progeny plant comprising the desired trait, andbackcrossing the selected F₁ progeny plant to a plant of soybean variety2940889. This method may further comprise the step of obtaining amolecular marker profile of soybean variety 2940889 and using themolecular marker profile to select for a progeny plant with the desiredtrait and the molecular marker profile of soybean cultivar 2940889. Inone embodiment, the desired trait is a mutant gene, gene, or transgenepresent in the donor parent.

Recurrent Selection and Mass Selection

Recurrent selection is a method used in a plant breeding program toimprove a population of plants. Soybean cultivar 2940889 is suitable foruse in a recurrent selection program. The method entails individualplants cross pollinating with each other to form progeny. The progenyare grown and the superior progeny selected by any number of selectionmethods, which include individual plant, half-sib progeny, full-sibprogeny, and selfed progeny. The selected progeny are cross pollinatedwith each other to form progeny for another population. This populationis planted and again superior plants are selected to cross pollinatewith each other. Recurrent selection is a cyclical process and thereforecan be repeated as many times as desired. The objective of recurrentselection is to improve the traits of a population. The improvedpopulation can then be used as a source of breeding material to obtainnew varieties for commercial or breeding use, including the productionof a synthetic cultivar. A synthetic cultivar is the resultant progenyformed by the intercrossing of several selected varieties.

Mass selection is a useful technique when used in conjunction withmolecular marker enhanced selection. In mass selection, seeds fromindividuals are selected based on phenotype or genotype. These selectedseeds are then bulked and used to grow the next generation. Bulkselection requires growing a population of plants in a bulk plot,allowing the plants to self-pollinate, harvesting the seed in bulk, andthen using a sample of the seed harvested in bulk to plant the nextgeneration. Also, instead of self-pollination, directed pollinationcould be used as part of the breeding program.

Mass and recurrent selections can be used to improve populations ofeither self- or cross-pollinating crops. A genetically variablepopulation of heterozygous individuals is either identified, or created,by intercrossing several different parents. The plants are selectedbased on individual superiority, outstanding progeny, or excellentcombining ability. The selected plants are intercrossed to produce a newpopulation in which further cycles of selection are continued.

Single-Seed Descent

The single-seed descent procedure in the strict sense refers to plantinga segregating population, harvesting a sample of one seed per plant, andusing the one-seed sample to plant the next generation. When thepopulation has been advanced from the F₂ to the desired level ofinbreeding, the plants from which lines are derived will each trace todifferent F₂ individuals. The number of plants in a population declineseach generation due to failure of some seeds to germinate or some plantsto produce at least one seed. As a result, not all of the F₂ plantsoriginally sampled in the population will be represented by a progenywhen generation advance is completed.

Multiple-Seed Procedure

In a multiple-seed procedure, soybean breeders commonly harvest one ormore pods from each plant in a population and thresh them together toform a bulk. Part of the bulk is used to plant the next generation andpart is put in reserve. The procedure has been referred to as modifiedsingle-seed descent or the pod-bulk technique.

The multiple-seed procedure has been used to save labor at harvest. Itis considerably faster to thresh pods with a machine than to remove oneseed from each by hand for the single-seed procedure. The multiple-seedprocedure also makes it possible to plant the same number of seeds of apopulation in each generation of inbreeding. Enough seeds are harvestedto make up for those plants that did not germinate or produce seed.

Mutation Breeding

Mutation breeding is another method of introducing new traits intosoybean variety 2940889. As used herein, a “mutation” is any change in anucleic acid sequence. Nonlimiting examples comprise insertions,deletions, duplications, substitutions, inversions, and translocationsof any nucleic acid sequence, regardless of how the mutation is broughtabout and regardless of how or whether the mutation alters the functionsor interactions of the nucleic acid. For example and without limitation,a mutation may produce altered enzymatic activity of a ribozyme, alteredbase pairing between nucleic acids (e.g. RNA interference interactions,DNA-RNA binding, etc.), altered mRNA folding stability, and/or how anucleic acid interacts with polypeptides (e.g. DNA-transcription factorinteractions, RNA-ribosome interactions, gRNA-endonuclease reactions,etc.). A mutation might result in the production of proteins withaltered amino acid sequences (e.g. missense mutations, nonsensemutations, frameshift mutations, etc.) and/or the production of proteinswith the same amino acid sequence (e.g. silent mutations). Certainsynonymous mutations may create no observed change in the plant whileothers that encode for an identical protein sequence nevertheless resultin an altered plant phenotype (e.g. due to codon usage bias, alteredsecondary protein structures, etc.). Mutations may occur within codingregions (e.g., open reading frames) or outside of coding regions (e.g.,within promoters, terminators, untranslated elements, or enhancers), andmay affect, for example and without limitation, gene expression levels,gene expression profiles, protein sequences, and/or sequences encodingRNA elements such as tRNAs, ribozymes, ribosome components, andmicroRNAs.

Methods disclosed herein are not limited to mutations made in thegenomic DNA of the plant nucleus. For example, in certain embodiments amutation is created in the genomic DNA of an organelle (e.g. a plastidand/or a mitochondrion). In certain embodiments, a mutation is createdin extrachromosomal nucleic acids (including RNA) of the plant, cell, ororganelle of a plant. Nonlimiting examples include creating mutations insupernumerary chromosomes (e.g. B chromosomes), plasmids, and/or vectorconstructs used to deliver nucleic acids to a plant. It is anticipatedthat new nucleic acid forms will be developed and yet fall within thescope of the claimed invention when used with the teachings describedherein.

Methods disclosed herein are not limited to certain techniques ofmutagenesis. Any method of creating a change in a nucleic acid of aplant can be used in conjunction with the disclosed invention, includingthe use of chemical mutagens (e.g. methanesulfonate, sodium azide,aminopurine, etc.), genome/gene editing techniques (e.g. CRISPR-liketechnologies, TALENs, zinc finger nucleases, and meganucleases),ionizing radiation (e.g. ultraviolet and/or gamma rays) temperaturealterations, long-term seed storage, tissue culture conditions,targeting induced local lesions in a genome, sequence-targeted and/orrandom recombinases, etc. It is anticipated that new methods of creatinga mutation in a nucleic acid of a plant will be developed and yet fallwithin the scope of the claimed invention when used with the teachingsdescribed herein.

Similarly, the embodiments disclosed herein are not limited to certainmethods of introducing nucleic acids into a plant and are not limited tocertain forms or structures that the introduced nucleic acids take. Anymethod of transforming a cell of a plant described herein with nucleicacids are also incorporated into the teachings of this innovation, andone of ordinary skill in the art will realize that the use of particlebombardment (e.g. using a gene-gun), Agrobacterium infection and/orinfection by other bacterial species capable of transferring DNA intoplants (e.g., Ochrobactrum sp., Ensifer sp., Rhizobium sp.), viralinfection, and other techniques can be used to deliver nucleic acidsequences into a plant described herein. Methods disclosed herein arenot limited to any size of nucleic acid sequences that are introduced,and thus one could introduce a nucleic acid comprising a singlenucleotide (e.g. an insertion) into a nucleic acid of the plant andstill be within the teachings described herein. Nucleic acids introducedin substantially any useful form, for example, on supernumerarychromosomes (e.g. B chromosomes), plasmids, vector constructs,additional genomic chromosomes (e.g. substitution lines), and otherforms is also anticipated. It is envisioned that new methods ofintroducing nucleic acids into plants and new forms or structures ofnucleic acids will be discovered and yet fall within the scope of theclaimed invention when used with the teachings described herein.

Mutations that occur spontaneously or are artificially induced can beuseful sources of variability for a plant breeder. The goal ofartificial mutagenesis is to increase the rate of mutation for a desiredcharacteristic. Mutation rates can be increased by many different meansincluding temperature, long-term seed storage, tissue cultureconditions, radiation; such as X-rays, Gamma rays (e.g., cobalt 60 orcesium 137), neutrons, (product of nuclear fission by uranium 235 in anatomic reactor), Beta radiation (emitted from radioisotopes such asphosphorus 32 or carbon 14), or ultraviolet radiation (preferably from2500 to 2900 nm), or chemical mutagens (such as base analogues(5-bromo-uracil)), related compounds (8-ethoxy caffeine), antibiotics(streptonigrin), alkylating agents (sulfur mustards, nitrogen mustards,epoxides, ethylenamines, sulfates, sulfonates, sulfones, lactones),azide, hydroxylamine, nitrous acid, or acridines. Once a desired traitis observed through mutagenesis the trait may then be incorporated intoexisting germplasm by traditional breeding techniques. Details ofmutation breeding can be found in Fehr, “Principles of CultivarDevelopment,” Macmillan Publishing Company (1993). In addition,mutations created in other soybean plants may be used to produce abackcross conversion of soybean cultivar 2940889 that comprises suchmutation.

Additional methods include, but are not limited to, expression vectorsintroduced into plant tissues using a direct gene transfer method, suchas microprojectile-mediated delivery, DNA injection, electroporation,and the like. More preferably, expression vectors are introduced intoplant tissues by using either microprojectile-mediated delivery with abiolistic device or by using Agrobacterium-mediated transformation.Transformant plants obtained with the protoplasm of the embodiments areintended to be within the scope of the embodiments.

Gene Editing Using CRISPR

Targeted gene editing can be done using CRISPR/Cas9 technology (Saunders& Joung, Nature Biotechnology, 32, 347-355, 2014). CRISPR is a type ofgenome editing system that stands for Clustered Regularly InterspacedShort Palindromic Repeats. This system and CRISPR-associated (Cas) genesenable organisms, such as select bacteria and archaea, to respond to andeliminate invading genetic material. Ishino, Y., et al. J. Bacteriol.169, 5429-5433 (1987). These repeats were known as early as the 1980s inE. coli, but Barrangou and colleagues demonstrated that S. thermophiluscan acquire resistance against a bacteriophage by integrating a fragmentof a genome of an infectious virus into its CRISPR locus. Barrangou, R.,et al. Science 315, 1709-1712 (2007). Many plants have already beenmodified using the CRISPR system, including soybean. See for example,Liu, J., et al. Genome Editing in Soybean with CRISPR/Cas9. Methods MolBiol. 2019. 1917:217-234.

Gene editing can also be done using crRNA-guided surveillance systemsfor gene editing. Additional information about crRNA-guided surveillancecomplex systems for gene editing can be found in the followingdocuments: U.S. Application Publication No. 2010/0076057 (Sontheimer etal., Target DNA Interference with crRNA); U.S. Application PublicationNo. 2014/0179006 (Feng, CRISPR-CAS Component Systems, Methods, andCompositions for Sequence Manipulation); U.S. Application PublicationNo. 2014/0294773 (Brouns et al., Modified Cascade Ribonucleoproteins andUses Thereof); Sorek et al., Annu. Rev. Biochem. 82:273-266, 2013; andWang, S. et al., Plant Cell Rep (2015) 34: 1473-1476.

Therefore, it is another embodiment to use the CRISPR system on soybeancultivar 2940889 to modify traits and resistances or tolerances topests, herbicides, and viruses.

Gene Editing Using TALENs

Transcription activator-like effector nucleases (TALENs) have beensuccessfully used to introduce targeted mutations via repair of doublestranded breaks (DSBs) either through non-homologous end joining (NHEJ),or by homology-directed repair (HDR) and homology-independent repair inthe presence of a donor template. Thus, TALENs are another mechanism fortargeted genome editing using soybean cultivar 2940889. The technique iswell known in the art; see for example Malzahn, Aimee et al. “Plantgenome editing with TALEN and CRISPR” Cell & bioscience vol. 7 21. 24Apr. 2017.

Therefore, it is another embodiment to use the TALENs system on soybeancultivar to modify traits and resistances or tolerances to pests,herbicides, and viruses.

Other Methods of Genome Editing

In addition to CRISPR and TALENs, two other types of engineerednucleases can be used for genome editing: engineered homingendonucleases/meganucleases (EMNs), and zinc finger nucleases (ZFNs).These methods are well known in the art. See for example, Petilino,Joseph F. “Genome editing in plants via designed zinc finger nucleases”In Vitro Cell Dev Biol Plant. 51(1): pp. 1-8 (2015); and Daboussi,Fayza, et al. “Engineering Meganuclease for Precise Plant GenomeModification” in Advances in New Technology for Targeted Modification ofPlant Genomes. Springer Science+Business. pp 21-38 (2015).

Therefore, it is another embodiment to use engineered nucleases onsoybean cultivar to modify traits and resistances or tolerances topests, herbicides, and viruses.

Single-Gene Conversions

When the term “soybean plant” is used in the context of an embodiment,this also includes any single gene conversions of that variety. The termsingle gene converted plant as used herein refers to those soybeanplants which are developed by a plant breeding technique calledbackcrossing wherein essentially all of the desired morphological andphysiological characteristics of a variety are recovered in addition tothe single gene transferred into the variety via the backcrossingtechnique. Backcrossing methods can be used with one embodiment toimprove or introduce a characteristic into the variety. The term“backcrossing” as used herein refers to the repeated crossing of ahybrid progeny back to the recurrent parent, i.e., backcrossing 1, 2, 3,4, 5, 6, 7, 8, or more times to the recurrent parent. The parentalsoybean plant that contributes the gene for the desired characteristicis termed the nonrecurrent or donor parent. This terminology refers tothe fact that the nonrecurrent parent is used one time in the backcrossprotocol and therefore does not recur. The parental soybean plant towhich the gene or genes from the nonrecurrent parent are transferred isknown as the recurrent parent as it is used for several rounds in thebackcrossing protocol (Poehlman & Sleper (1994); Fehr, Principles ofCultivar Development, pp. 261-286 (1987)). In a typical backcrossprotocol, the original variety of interest (recurrent parent) is crossedto a second variety (nonrecurrent parent) that carries the single geneof interest to be transferred. The resulting progeny from this cross arethen crossed again to the recurrent parent and the process is repeateduntil a soybean plant is obtained wherein essentially all of the desiredmorphological and physiological characteristics of the recurrent parentare recovered in the converted plant, in addition to the singletransferred gene from the nonrecurrent parent.

The selection of a suitable recurrent parent is an important step for asuccessful backcrossing procedure. The goal of a backcross protocol isto alter or substitute a single trait or characteristic in the originalvariety. To accomplish this, a single gene of the recurrent variety ismodified or substituted with the desired gene from the nonrecurrentparent, while retaining essentially all of the rest of the desiredgenetic, and therefore the desired physiological and morphologicalconstitution of the original variety. The choice of the particularnonrecurrent parent will depend on the purpose of the backcross; one ofthe major purposes is to add some agronomically important trait to theplant. The exact backcrossing protocol will depend on the characteristicor trait being altered to determine an appropriate testing protocol.Although backcrossing methods are simplified when the characteristicbeing transferred is a dominant allele, a recessive allele may also betransferred. In this instance, it may be necessary to introduce a testof the progeny to determine if the desired characteristic has beensuccessfully transferred.

Many single gene traits have been identified that are not regularlyselected for in the development of a new variety but that can beimproved by backcrossing techniques. Single gene traits may or may notbe transgenic. Examples of these traits include, but are not limited to,male sterility, waxy starch, herbicide resistance, resistance forbacterial, fungal, or viral disease, insect resistance, male fertility,enhanced nutritional quality, industrial usage, yield stability, andyield enhancement. These genes are generally inherited through thenucleus. Several of these single gene traits are described in U.S. Pat.Nos. 5,959,185, 5,973,234, and 5,977,445, the disclosures of which arespecifically hereby incorporated by reference.

Introduction of a New Trait or Locus into Soybean Cultivar 2940889

Variety 2940889 represents a new variety into which a new locus or traitmay be introgressed. Direct transformation and backcrossing representtwo important methods that can be used to accomplish such anintrogression. The term backcross conversion and single locus conversionare used interchangeably to designate the product of a backcrossingprogram.

Backcross Conversions of Soybean Cultivar 2940889

A backcross conversion of soybean cultivar 2940889 occurs when DNAsequences are introduced through backcrossing (Hallauer, et al., “CornBreeding,” Corn and Corn Improvements, No. 18, pp. 463-481 (1988)), withsoybean cultivar 2940889 utilized as the recurrent parent. Bothnaturally occurring and transgenic DNA sequences may be introducedthrough backcrossing techniques. A backcross conversion may produce aplant with a trait or locus conversion in at least two or morebackcrosses, including at least 2 crosses, at least 3 crosses, at least4 crosses, at least 5 crosses, and the like. Molecular marker assistedbreeding or selection may be utilized to reduce the number ofbackcrosses necessary to achieve the backcross conversion. For example,see, Openshaw, S. J., et al., Marker-assisted Selection in BackcrossBreeding, Proceedings Symposium of the Analysis of Molecular Data, CropScience Society of America, Corvallis, Oreg. (August 1994), where it isdemonstrated that a backcross conversion can be made in as few as twobackcrosses. In one embodiment, a breeder can combine the teachingsherein with high-density molecular marker profiles spanningsubstantially the entire soybean genome to estimate the value ofselecting certain candidates in a breeding program in a process commonlyknown as genome/genomic selection.

The complexity of the backcross conversion method depends on the type oftrait being transferred (single genes or closely linked genes ascompared to unlinked genes), the level of expression of the trait, thetype of inheritance (cytoplasmic or nuclear), and the types of parentsincluded in the cross. It is understood by those of ordinary skill inthe art that for single gene traits that are relatively easy toclassify, the backcross method is effective and relatively easy tomanage. (See, Hallauer, et al., Corn and Corn Improvement, Sprague andDudley, Third Ed. (1998)). Desired traits that may be transferredthrough backcross conversion include, but are not limited to, sterility(nuclear and cytoplasmic), fertility restoration, nutritionalenhancements, drought tolerance, nitrogen utilization, altered fattyacid profile, low phytate, industrial enhancements, disease resistance(bacterial, fungal, or viral), insect resistance, and herbicideresistance. In addition, an introgression site itself, such as an FRTsite, Lox site, or other site-specific integration site, may be insertedby backcrossing and utilized for direct insertion of one or more genesof interest into a specific plant variety. In some embodiments, thenumber of loci that may be backcrossed into soybean cultivar 2940889 isat least 1, 2, 3, 4, or 5, and/or no more than 6, 5, 4, 3, or 2. Asingle locus may contain several transgenes, such as a transgene fordisease resistance that, in the same expression vector, also contains atransgene for herbicide resistance. The gene for herbicide resistancemay be used as a selectable marker and/or as a phenotypic trait. Asingle locus conversion of site-specific integration system allows forthe integration of multiple genes at the converted loci.

The backcross conversion may result from either the transfer of adominant allele or a recessive allele. Selection of progeny containingthe trait of interest is accomplished by direct selection for a traitassociated with a dominant allele. Transgenes transferred viabackcrossing typically function as a dominant single gene trait and arerelatively easy to classify. Selection of progeny for a trait that istransferred via a recessive allele requires growing and selfing thefirst backcross generation to determine which plants carry the recessivealleles. Recessive traits may require additional progeny testing insuccessive backcross generations to determine the presence of the locusof interest. The last backcross generation is usually selfed to givepure breeding progeny for the gene(s) being transferred, although abackcross conversion with a stably introgressed trait may also bemaintained by further backcrossing to the recurrent parent withselection for the converted trait.

Along with selection for the trait of interest, progeny are selected forthe phenotype of the recurrent parent. The backcross is a form ofinbreeding, and the features of the recurrent parent are automaticallyrecovered after successive backcrosses. Poehlman, Breeding Field Crops,p. 204 (1987). Poehlman suggests from one to four or more backcrosses,but as noted above, the number of backcrosses necessary can be reducedwith the use of molecular markers. Other factors, such as a geneticallysimilar donor parent, may also reduce the number of backcrossesnecessary. As noted by Poehlman, backcrossing is easiest for simplyinherited, dominant, and easily recognized traits.

One process for adding or modifying a trait or locus in soybean variety2940889 comprises crossing soybean cultivar 2940889 plants grown fromsoybean cultivar 2940889 seed with plants of another soybean varietythat comprise the desired trait or locus, selecting F₁ progeny plantsthat comprise the desired trait or locus to produce selected F₁ progenyplants, crossing the selected progeny plants with the soybean cultivar2940889 plants to produce backcross progeny plants, selecting forbackcross progeny plants that have the desired trait or locus and themorphological characteristics of soybean variety 2940889 to produceselected backcross progeny plants, and backcrossing to soybean cultivar2940889 three or more times in succession to produce selected fourth orhigher backcross progeny plants that comprise said trait or locus. Themodified soybean cultivar 2940889 may be further characterized as havingthe physiological and morphological characteristics of soybean variety2940889 listed in Table 1 as determined at the 5% significance levelwhen grown in the same environmental conditions and/or may becharacterized by percent similarity or identity to soybean cultivar2940889 as determined by SSR markers. The above method may be utilizedwith fewer backcrosses in appropriate situations, such as when the donorparent is highly related or markers are used in the selection step.Desired traits that may be used include those nucleic acids known in theart, some of which are listed herein, that will affect traits throughnucleic acid expression or inhibition. Desired loci include theintrogression of FRT, Lox, and other sites for site specificintegration, which may also affect a desired trait if a functionalnucleic acid is inserted at the integration site.

In addition, the above process and other similar processes describedherein may be used to produce first generation progeny soybean seed byadding a step at the end of the process that comprises crossing soybeancultivar 2940889 with the introgressed trait or locus with a differentsoybean plant and harvesting the resultant first-generation progenysoybean seed.

Molecular Techniques Using Soybean Cultivar 2940889

The advent of new molecular biological techniques has allowed theisolation and characterization of genetic elements with specificfunctions, such as encoding specific protein products. Scientists in thefield of plant biology developed a strong interest in engineering thegenome of plants to contain and express foreign genetic elements, oradditional, or modified versions of native or endogenous geneticelements in order to “alter” (the utilization of up-regulation,down-regulation, or gene silencing) the traits of a plant in a specificmanner. Any DNA sequences, whether from a different species or from thesame species, which are introduced into the genome using transformationor various breeding methods are referred to herein collectively as“transgenes.” In some embodiments, a transgenic variant of soybeancultivar 2940889 may contain at least one transgene but could contain atleast 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and/or no more than 15, 14, 13, 12,11, 10, 9, 8, 7, 6, 5, 4, 3, or 2. Over the last fifteen to twenty yearsseveral methods for producing transgenic plants have been developed, andanother embodiment also relates to transgenic variants of the claimedsoybean variety 2940889.

Nucleic acids or polynucleotides refer to RNA or DNA that is linear orbranched, single or double stranded, or a hybrid thereof. The term alsoencompasses RNA/DNA hybrids. These terms also encompass untranslatedsequence located at both the 3′ and 5′ ends of the coding region of thegene: at least about 1000 nucleotides of sequence upstream from the 5′end of the coding region and at least about 200 nucleotides of sequencedownstream from the 3′ end of the coding region of the gene. Less commonbases, such as inosine, 5-methylcytosine, 6-methyladenine, hypoxanthineand others can also be used for antisense, dsRNA and ribozyme pairing.For example, polynucleotides that contain C-5 propyne analogues ofuridine and cytidine have been shown to bind RNA with high affinity andto be potent antisense inhibitors of gene expression. Othermodifications, such as modification to the phosphodiester backbone, orthe 2′-hydroxy in the ribose sugar group of the RNA can also be made.The antisense polynucleotides and ribozymes can consist entirely ofribonucleotides, or can contain mixed ribonucleotides anddeoxyribonucleotides. The polynucleotides of the embodiments may beproduced by any means, including genomic preparations, cDNApreparations, in-vitro synthesis, RT-PCR, and in vitro or in vivotranscription.

One embodiment is a process for producing soybean variety 2940889further comprising a desired trait, said process comprising introducinga transgene that confers a desired trait to a soybean plant of variety2940889. Another embodiment is the product produced by this process. Inone embodiment, the desired trait may be one or more of herbicideresistance, insect resistance, disease resistance, decreased phytate, ormodified fatty acid or carbohydrate metabolism. The specific gene may beany known in the art or listed herein, including: a polynucleotideconferring resistance to imidazolinone, dicamba, sulfonylurea,glyphosate, glufosinate, triazine, PPO-inhibitor herbicides,benzonitrile, cyclohexanedione, phenoxy proprionic acid, andL-phosphinothricin; a polynucleotide encoding a Bacillus thuringiensispolypeptide; a polynucleotide encoding phytase, FAD-2, FAD-3, galactinolsynthase, or a raffinose synthetic enzyme; or a polynucleotideconferring resistance to soybean cyst nematode, brown stem rot,Phytophthora root rot, soybean mosaic virus, or sudden death syndrome.

Numerous methods for plant transformation have been developed, includingbiological and physical plant transformation protocols. See, forexample, Miki et al., “Procedures for Introducing Foreign DNA intoPlants,” in Methods in Plant Molecular Biology and Biotechnology, Glickand Thompson Eds., CRC Press, Inc., Boca Raton, pp. 67-88 (1993), andArmstrong, “The First Decade of Maize Transformation: A Review andFuture Perspective,” Maydica, 44:101-109 (1999). In addition, expressionvectors and in vitro culture methods for plant cell or tissuetransformation and regeneration of plants are available. See, forexample, Gruber, et al., “Vectors for Plant Transformation,” in Methodsin Plant Molecular Biology and Biotechnology, Glick and Thompson Eds.,CRC Press, Inc., Boca Raton, pp. 89-119 (1993).

A genetic trait which has been engineered into the genome of aparticular soybean plant may then be moved into the genome of anothervariety using traditional breeding techniques that are well known in theplant breeding arts. For example, a backcrossing approach is commonlyused to move a transgene from a transformed soybean variety into analready developed soybean variety, and the resulting backcrossconversion plant would then comprise the transgene(s).

Various genetic elements can be introduced into the plant genome usingtransformation. These elements include, but are not limited to, genes,coding sequences, inducible, constitutive and tissue specific promoters,enhancing sequences, and signal and targeting sequences. For example,see the traits, genes, and transformation methods listed in U.S. Pat.No. 6,118,055.

Breeding with Molecular Markers

Molecular markers, which includes markers identified through the use oftechniques such as Isozyme Electrophoresis, Restriction Fragment LengthPolymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs),Arbitrarily Primed Polymerase Chain Reaction (AP-PCR), DNA AmplificationFingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs),Amplified Fragment Length Polymorphisms (AFLPs), Simple Sequence Repeats(SSRs), and Single Nucleotide Polymorphisms (SNPs), may be used in plantbreeding methods utilizing soybean cultivar 2940889.

Isozyme Electrophoresis and RFLPs have been widely used to determinegenetic composition. Shoemaker and Olsen, Molecular Linkage Map ofSoybean (Glycine max L. Merr.), pp. 6.131-6.138 (1993). In S. J. O'Brien(ed.), Genetic Maps: Locus Maps of Complex Genomes, Cold Spring HarborLaboratory Press, Cold Spring Harbor, N.Y., developed a moleculargenetic linkage map that consisted of 25 linkage groups with about 365RFLP, 11 RAPD (random amplified polymorphic DNA), 3 classical markers,and 4 isozyme loci. See also, Shoemaker, R. C., 1994 RFLP Map ofSoybean, pp. 299-309; In R. L. Phillips and I. K. Vasil (ed.), DNA-basedmarkers in plants, Kluwer Academic Press Dordrecht, the Netherlands.

SSR technology is currently the most efficient and practical markertechnology. More marker loci can be routinely used, and more alleles permarker locus can be found, using SSRs in comparison to RFLPs. Forexample, Diwan and Cregan described highly polymorphic microsatelliteloci in soybean with as many as 26 alleles. (Diwan, N., and Cregan. P.B., Automated sizing of fluorescent-labeled simple sequence repeat (SSR)markers to assay genetic variation in Soybean, Theor. Appl. Genet.,95:220-225 (1997)). Single Nucleotide Polymorphisms may also be used toidentify the unique genetic composition of the embodiment(s) and progenyvarieties retaining that unique genetic composition. Various molecularmarker techniques may be used in combination to enhance overallresolution.

Soybean DNA molecular marker linkage maps have been rapidly constructedand widely implemented in genetic studies. One such study is describedin Cregan, et. al, “An Integrated Genetic Linkage Map of the SoybeanGenome,” Crop Science, 39:1464-1490 (1999). Sequences and PCR conditionsof SSR Loci in Soybean, as well as the most current genetic map, may befound in Soybase on the World Wide Web.

Quantitative trait loci (QTL) refer to genetic loci that control to somedegree numerically representable traits that are usually continuouslydistributed. One use of molecular markers is Quantitative Trait Loci(QTL) mapping. QTL mapping is the use of markers, which are known to beclosely linked to alleles that have measurable effects on a quantitativetrait. Selection in the breeding process is based upon the accumulationof markers linked to the positive effecting alleles and/or theelimination of the markers linked to the negative effecting alleles fromthe plant's genome.

Molecular markers can also be used during the breeding process for theselection of qualitative traits. For example, markers closely linked toalleles or markers containing sequences within the actual alleles ofinterest can be used to select plants that contain the alleles ofinterest during a backcrossing breeding program. The markers can also beused to select for the genome of the recurrent parent and against thegenome of the donor parent. Using this procedure can minimize the amountof genome from the donor parent that remains in the selected plants. Itcan also be used to reduce the number of crosses back to the recurrentparent needed in a backcrossing program. The use of molecular markers inthe selection process is often called genetic marker enhanced selection.Molecular markers may also be used to identify and exclude certainsources of germplasm as parental varieties or ancestors of a plant byproviding a means of tracking genetic profiles through crosses.

Production of Double Haploids

The production of double haploids can also be used for the developmentof plants with a homozygous phenotype in the breeding program. Forexample, a soybean plant for which soybean cultivar 2940889 is a parentcan be used to produce double haploid plants. Double haploids areproduced by the doubling of a set of chromosomes (1N) from aheterozygous plant to produce a completely homozygous individual. Forexample, see, Wan, et al., “Efficient Production of Doubled HaploidPlants Through Colchicine Treatment of Anther-Derived Maize Callus,”Theoretical and Applied Genetics, 77:889-892 (1989) and U.S. Pat. No.7,135,615. This can be advantageous because the process omits thegenerations of selfing needed to obtain a homozygous plant from aheterozygous source.

Haploid induction systems have been developed for various plants toproduce haploid tissues, plants and seeds. The haploid induction systemcan produce haploid plants from any genotype by crossing a selected line(as female) with an inducer line. Such inducer lines for maize includeStock 6 (Coe, Am. Nat., 93:381-382 (1959); Sharkar and Coe, Genetics,54:453-464 (1966); KEMS (Deimling, Roeber, and Geiger, Vortr.Pflanzenzuchtg, 38:203-224 (1997); or KMS and ZMS (Chalyk, Bylich &Chebotar, MNL, 68:47 (1994); Chalyk & Chebotar, Plant Breeding,119:363-364 (2000)); and indeterminate gametophyte (ig) mutation(Kermicle, Science, 166:1422-1424 (1969)). The disclosures of which areincorporated herein by reference.

Methods for obtaining haploid plants are also disclosed in Kobayashi,M., et al., Journ. of Heredity, 71(1):9-14 (1980); Pollacsek, M.,Agronomie (Paris) 12(3):247-251 (1992); Cho-Un-Haing, et al., Journ. ofPlantBiol., 39(3):185-188 (1996); Verdoodt, L., et al., 96(2):294-300(February 1998); Chalyk, et al., Maize Genet Coop., Newsletter 68:47(1994).

Thus, an embodiment is a process for making a substantially homozygoussoybean cultivar 2940889 progeny plant by producing or obtaining a seedfrom the cross of soybean cultivar 2940889 and another soybean plant andapplying double haploid methods to the F₁ seed or F₁ plant or to anysuccessive filial generation. Based on studies in maize and currentlybeing conducted in soybean, such methods would decrease the number ofgenerations required to produce a variety with similar genetics orcharacteristics to soybean cultivar 2940889. See, Bernardo, R. andKahler, A. L., Theor. Appl. Genet., 102:986-992 (2001).

In particular, a process of making seed retaining the molecular markerprofile of soybean variety 2940889 is contemplated, such processcomprising obtaining or producing F₁ seed for which soybean variety2940889 is a parent, inducing doubled haploids to create progeny withoutthe occurrence of meiotic segregation, obtaining the molecular markerprofile of soybean variety 2940889, and selecting progeny that retainthe molecular marker profile of soybean cultivar 2940889.

Descriptions of other breeding methods that are commonly used fordifferent traits and crops can be found in one of several referencebooks (e.g., Allard (1960); Simmonds (1979); Sneep, et al. (1979); Fehr(1987)).

Expression Vectors for Soybean Transformation: Marker Genes

Plant transformation involves the construction of an expression vectorwhich will function in plant cells. Such a vector comprises DNAcomprising a gene under control of, or operatively linked to, aregulatory element (for example, a promoter). Expression vectors includeat least one genetic marker operably linked to a regulatory element (forexample, a promoter) that allows transformed cells containing the markerto be either recovered by negative selection, i.e., inhibiting growth ofcells that do not contain the selectable marker gene, or by positiveselection, i.e., screening for the product encoded by the geneticmarker. Many commonly used selectable marker genes for planttransformation are well-known in the transformation arts, and include,for example, genes that code for enzymes that metabolically detoxify aselective chemical agent which may be an antibiotic or an herbicide, orgenes that encode an altered target which is insensitive to theinhibitor. A few positive selection methods are also known in the art.

One commonly used selectable marker gene for plant transformation is theneomycin phosphotransferase II (nptII) gene which, when under thecontrol of plant regulatory signals, confers resistance to kanamycin.Fraley, et al., Proc. Natl. Acad. Sci. USA, 80:4803 (1983).

Another commonly used selectable marker gene is the hygromycinphosphotransferase gene which confers resistance to the antibiotichygromycin. Vanden Elzen, et al., Plant Mol. Biol., 5:299 (1985).

Additional selectable marker genes of bacterial origin that conferresistance to antibiotics include gentamycin acetyl transferase,streptomycin phosphotransferase and aminoglycoside-3′-adenyltransferase, the bleomycin resistance determinant (Hayford, et al.,Plant Physiol., 86:1216 (1988); Jones, et al., Mol. Gen. Genet., 210:86(1987); Svab, et al., Plant Mol. Biol., 14:197 (1990); Hille, et al.,Plant Mol. Biol., 7:171 (1986)). Other selectable marker genes conferresistance to herbicides such as glyphosate, glufosinate, or bromoxynil(Comai, et al., Nature, 317:741-744 (1985); Gordon-Kamm, et al., PlantCell, 2:603-618 (1990); Stalker, et al., Science, 242:419-423 (1988)).

Selectable marker genes for plant transformation not of bacterial origininclude, for example, mouse dihydrofolate reductase, plant5-enolpyruvylshikimate-3-phosphate synthase, and plant acetolactatesynthase (Eichholtz, et al., Somatic Cell Mol. Genet., 13:67 (1987);Shah, et al., Science, 233:478 (1986); Charest, et al., Plant Cell Rep.,8:643 (1990)).

Another class of marker genes for plant transformation requiresscreening of presumptively transformed plant cells, rather than directgenetic selection of transformed cells, for resistance to a toxicsubstance such as an antibiotic. These genes are particularly useful toquantify or visualize the spatial pattern of expression of a gene inspecific tissues and are frequently referred to as reporter genesbecause they can be fused to a gene or gene regulatory sequence for theinvestigation of gene expression. Commonly used genes for screeningpresumptively transformed cells include β-glucuronidase (GUS),β-galactosidase, luciferase, and chloramphenicol acetyltransferase(Jefferson, R. A., Plant Mol. Biol. Rep., 5:387 (1987); Teeri, et al.,EMBO J., 8:343 (1989); Koncz, et al., Proc. Natl. Acad. Sci. USA, 84:131(1987); DeBlock, et al., EMBO J., 3:1681 (1984)).

In vivo methods for visualizing GUS activity that do not requiredestruction of plant tissue are available (Molecular Probes, Publication2908, IMAGENE GREEN, pp. 1-4 (1993); Naleway, et al., J. Cell Biol.,115:151a (1991)). However, these in-vivo methods for visualizing GUSactivity have not proven useful for recovery of transformed cellsbecause of low sensitivity, high fluorescent backgrounds, andlimitations associated with the use of luciferase genes as selectablemarkers.

More recently, a gene encoding Green Fluorescent Protein (GFP) has beenutilized as a marker for gene expression in prokaryotic and eukaryoticcells (Chalfie, et al., Science, 263:802 (1994)). GFP and mutants of GFPmay be used as screenable markers.

Expression Vectors for Soybean Transformation: Promoters

Genes included in expression vectors must be driven by a nucleotidesequence comprising a regulatory element (for example, a promoter).Several types of promoters are well known in the transformation arts asare other regulatory elements that can be used alone or in combinationwith promoters.

As used herein, “promoter” includes reference to a region of DNAupstream from the start of transcription and involved in recognition andbinding of RNA polymerase and other proteins to initiate transcription.A “plant promoter” is a promoter capable of initiating transcription inplant cells. Examples of promoters under developmental control includepromoters that preferentially initiate transcription in certain tissues,such as leaves, roots, seeds, fibers, xylem vessels, tracheids, orsclerenchyma. Such promoters are referred to as “tissue-preferred.”Promoters that initiate transcription only in a certain tissue arereferred to as “tissue-specific.” A “cell-type” specific promoterprimarily drives expression in certain cell types in one or more organs,for example, vascular cells in roots or leaves. An “inducible” promoteris a promoter which is under environmental control. Examples ofenvironmental conditions that may affect transcription by induciblepromoters include anaerobic conditions or the presence of light.Tissue-specific, tissue-preferred, cell-type specific, and induciblepromoters constitute the class of “non-constitutive” promoters. A“constitutive” promoter is a promoter that is active under mostenvironmental conditions.

A. Inducible Promoters: An inducible promoter is operably linked to agene for expression in soybean. Optionally, the inducible promoter isoperably linked to a nucleotide sequence encoding a signal sequencewhich is operably linked to a gene for expression in soybean. With aninducible promoter, the rate of transcription increases in response toan inducing agent.

Any inducible promoter can be used in an embodiment(s). See, Ward, etal., Plant Mol. Biol., 22:361-366 (1993). Exemplary inducible promotersinclude, but are not limited to, that from the ACEI system whichresponds to copper (Mett, et al., Proc. Natl. Acad. Sci. USA,90:4567-4571 (1993)); In2 gene from maize which responds tobenzenesulfonamide herbicide safeners (Hershey, et al., Mol. GenGenetics, 227:229-237 (1991); Gatz, et al., Mol. Gen. Genetics,243:32-38 (1994)); or Tet repressor from Tn10 (Gatz, et al., Mol. Gen.Genetics, 227:229-237 (1991)). An inducible promoter is a promoter thatresponds to an inducing agent to which plants do not normally respond.An exemplary inducible promoter is the inducible promoter from a steroidhormone gene, the transcriptional activity of which is induced by aglucocorticosteroid hormone (Schena, et al., Proc. Natl. Acad. Sci. USA,88:0421 (1991)).

B. Constitutive Promoters: A constitutive promoter is operably linked toa gene for expression in soybean or the constitutive promoter isoperably linked to a nucleotide sequence encoding a signal sequencewhich is operably linked to a gene for expression in soybean.

Many different constitutive promoters can be utilized in anembodiment(s). Exemplary constitutive promoters include, but are notlimited to, the promoters from plant viruses such as the 35S promoterfrom CaMV (Odell, et al., Nature, 313:810-812 (1985)) and the promotersfrom such genes as rice actin (McElroy, et al., Plant Cell, 2:163-171(1990)); ubiquitin (Christensen, et al., Plant Mol. Biol., 12:619-632(1989); Christensen, et al., Plant Mol. Biol., 18:675-689 (1992)); pEMU(Last, et al., Theor. Appl. Genet., 81:581-588 (1991)); MAS (Velten, etal., EMBO J., 3:2723-2730 (1984)); and maize H3 histone (Lepetit, etal., Mol. Gen. Genetics, 231:276-285 (1992); Atanassova, et al., PlantJournal, 2 (3):291-300 (1992)). The ALS promoter, XbaI/NcoI fragment 5′to the Brassica napus ALS3 structural gene (or a nucleotide sequencesimilarity to said XbaI/NcoI fragment), represents a particularly usefulconstitutive promoter. See, U.S. Pat. No. 5,659,026.

C. Tissue-Specific or Tissue-Preferred Promoters: A tissue-specificpromoter is operably linked to a gene for expression in soybean.Optionally, the tissue-specific promoter is operably linked to anucleotide sequence encoding a signal sequence which is operably linkedto a gene for expression in soybean. Plants transformed with a gene ofinterest operably linked to a tissue-specific promoter produce theprotein product of the transgene exclusively, or preferentially, in aspecific tissue.

Any tissue-specific or tissue-preferred promoter can be utilized in anembodiment(s). Exemplary tissue-specific or tissue-preferred promotersinclude, but are not limited to, a root-preferred promoter such as thatfrom the phaseolin gene (Murai, et al., Science, 23:476-482 (1983);Sengupta-Gopalan, et al., Proc. Natl. Acad. Sci. USA, 82:3320-3324(1985)); a leaf-specific and light-induced promoter such as that fromcab or rubisco (Simpson, et al., EMBO J., 4(11):2723-2729 (1985); Timko,et al., Nature, 318:579-582 (1985)); an anther-specific promoter such asthat from LAT52 (Twell, et al., Mol. Gen. Genetics, 217:240-245 (1989));a pollen-specific promoter such as that from Zm13 (Guerrero, et al.,Mol. Gen. Genetics, 244:161-168 (1993)); or a microspore-preferredpromoter such as that from apg (Twell, et al., Sex. Plant Reprod.,6:217-224 (1993)).

Signal Sequences for Targeting Proteins to Subcellular Compartments

Transport of a protein produced by transgenes to a subcellularcompartment, such as the chloroplast, vacuole, peroxisome, glyoxysome,cell wall, or mitochondrion, or for secretion into the apoplast, isaccomplished by means of operably linking the nucleotide sequenceencoding a signal sequence to the 5′ and/or 3′ region of a gene encodingthe protein of interest. Targeting sequences at the 5′ and/or 3′ end ofthe structural gene may determine during protein synthesis andprocessing where the encoded protein is ultimately compartmentalized.

The presence of a signal sequence directs a polypeptide to either anintracellular organelle or subcellular compartment or for secretion tothe apoplast. Many signal sequences are known in the art. See, forexample, Becker, et al., Plant Mol. Biol., 20:49 (1992); Knox, C., etal., Plant Mol. Biol., 9:3-17 (1987); Lerner, et al., Plant Physiol.,91:124-129 (1989); Frontes, et al., Plant Cell, 3:483-496 (1991);Matsuoka, et al., Proc. Natl. Acad. Sci., 88:834 (1991); Gould, et al.,J Cell. Biol., 108:1657 (1989); Creissen, et al., Plant 1, 2:129 (1991);Kalderon, et al., Cell, 39:499-509 (1984); Steifel, et al., Plant Cell,2:785-793 (1990).

Foreign Protein Genes and Agronomic Genes: Transformation

With transgenic plants according to one embodiment, a foreign proteincan be produced in commercial quantities. Thus, techniques for theselection and propagation of transformed plants, which are wellunderstood in the art, yield a plurality of transgenic plants which areharvested in a conventional manner, and a foreign protein can then beextracted from a tissue of interest or from total biomass. Proteinextraction from plant biomass can be accomplished by known methods whichare discussed, for example, by Heney and Orr, Anal. Biochem., 114:92-6(1981).

According to an embodiment, the transgenic plant provided for commercialproduction of foreign protein is a soybean plant. In another embodiment,the biomass of interest is seed. For the relatively small number oftransgenic plants that show higher levels of expression, a genetic mapcan be generated, primarily via conventional RFLP, PCR, and SSRanalysis, which identifies the approximate chromosomal location of theintegrated DNA molecule. For exemplary methodologies in this regard,see, Glick and Thompson, Methods in Plant Molecular Biology andBiotechnology, CRC Press, Inc., Boca Raton, 269:284 (1993). Mapinformation concerning chromosomal location is useful for proprietaryprotection of a subject transgenic plant.

Wang, et al. discuss “Large Scale Identification, Mapping and Genotypingof Single-Nucleotide Polymorphisms in the Human Genome,” Science,280:1077-1082 (1998), and similar capabilities are becoming increasinglyavailable for the soybean genome. Map information concerning chromosomallocation is useful for proprietary protection of a subject transgenicplant. If unauthorized propagation is undertaken and crosses made withother germplasm, the map of the integration region can be compared tosimilar maps for suspect plants to determine if the latter have a commonparentage with the subject plant. Map comparisons would involvehybridizations, RFLP, PCR, SSR, and sequencing, all of which areconventional techniques. SNPs may also be used alone or in combinationwith other techniques.

Likewise, by means of one embodiment, plants can be geneticallyengineered to express various phenotypes of agronomic interest. Throughthe transformation of soybean, the expression of genes can be altered toenhance disease resistance, insect resistance, herbicide resistance,agronomic, grain quality, and other traits. Transformation can also beused to insert DNA sequences which control or help controlmale-sterility. DNA sequences native to soybean, as well as non-nativeDNA sequences, can be transformed into soybean and used to alter levelsof native or non-native proteins. Various promoters, targetingsequences, enhancing sequences, and other DNA sequences can be insertedinto the genome for the purpose of altering the expression of proteins.The interruption or suppression of the expression of a gene at the levelof transcription or translation (also known as gene silencing or genesuppression) is desirable for several aspects of genetic engineering inplants.

Many techniques for gene silencing are well-known to one of skill in theart, including, but not limited to, knock-outs (such as by insertion ofa transposable element such as Mu (Vicki Chandler, The Maize Handbook,Ch. 118 (Springer-Verlag 1994)) or other genetic elements such as a FRT,Lox, or other site specific integration sites; antisense technology(see, e.g., Sheehy, et al., PNAS USA, 85:8805-8809 (1988) and U.S. Pat.Nos. 5,107,065, 5,453,566, and 5,759,829); co-suppression (e.g., Taylor,Plant Cell, 9:1245 (1997); Jorgensen, Trends Biotech., 8(12):340-344(1990); Flavell, PNAS USA, 91:3490-3496 (1994); Finnegan, et al.,Bio/Technology, 12:883-888 (1994); Neuhuber, et al., Mol. Gen. Genet.,244:230-241 (1994)); RNA interference (Napoli, et al., Plant Cell,2:279-289 (1990); U.S. Pat. No. 5,034,323; Sharp, Genes Dev., 13:139-141(1999); Zamore, et al., Cell, 101:25-33 (2000); Montgomery, et al., PNASUSA, 95:15502-15507 (1998)), virus-induced gene silencing (Burton, etal., Plant Cell, 12:691-705 (2000); Baulcombe, Curr. Op. Plant Bio.,2:109-113 (1999)); target-RNA-specific ribozymes (Haseloff, et al.,Nature, 334:585-591 (1988)); hairpin structures (Smith, et al., Nature,407:319-320 (2000); U.S. Pat. Nos. 6,423,885, 7,138,565, 6,753,139, and7,713,715); MicroRNA (Aukerman & Sakai, Plant Cell, 15:2730-2741(2003)); ribozymes (Steinecke, et al., EMBO J., 11:1525 (1992);Perriman, et al., Antisense Res. Dev., 3:253 (1993)); oligonucleotidemediated targeted modification (e.g., U.S. Pat. Nos. 6,528,700 and6,911,575); Zn-finger targeted molecules (e.g., U.S. Pat. Nos.7,151,201, 6,453,242, 6,785,613, 7,177,766 and 7,788,044); and othermethods or combinations of the above methods known to those of skill inthe art.

Methods for Soybean Transformation

Numerous methods for plant transformation have been developed includingbiological and physical plant transformation protocols. See, forexample, Miki, et al., “Procedures for Introducing Foreign DNA intoPlants,” in Methods in Plant Molecular Biology and Biotechnology, Glickand Thompson Eds., CRC Press, Inc., Boca Raton, pp. 67-88 (1993). Inaddition, expression vectors and in-vitro culture methods for plant cellor tissue transformation and regeneration of plants are available. See,for example, Gruber, et al., “Vectors for Plant Transformation,” inMethods in Plant Molecular Biology and Biotechnology, Glick and ThompsonEds., CRC Press, Inc., Boca Raton, pp. 89-119 (1993).

A. Agrobacterium-mediated Transformation: One method for introducing anexpression vector into plants is based on the natural transformationsystem of Agrobacterium. See, for example, Horsch, et al., Science,227:1229 (1985). A. tumefaciens and A. rhizogenes are plant pathogenicsoil bacteria which genetically transform plant cells. The Ti and Riplasmids of A. tumefaciens and A. rhizogenes, respectively, carry genesresponsible for genetic transformation of the plant. See, for example,Kado, C. I., Crit. Rev. Plant Sci., 10:1 (1991). Descriptions ofAgrobacterium vector systems and methods for Agrobacterium-mediated genetransfer are provided by Gruber, et al., supra, Miki, et al., supra, andMoloney, et al., Plant Cell Reports, 8:238 (1989). See also, U.S. Pat.No. 5,563,055 (Townsend and Thomas), issued Oct. 8, 1996.

B. Direct Gene Transfer: Several methods of plant transformation,collectively referred to as direct gene transfer, have been developed asan alternative to Agrobacterium-mediated transformation. A generallyapplicable method of plant transformation is microprojectile-mediatedtransformation where DNA is carried on the surface of microprojectilesmeasuring 1 to 4 μm. The expression vector is introduced into planttissues with a biolistic device that accelerates the microprojectiles tospeeds of 300 to 600 m/s which is sufficient to penetrate plant cellwalls and membranes. Sanford, et al., Part. Sci. Technol., 5:27 (1987);Sanford, J. C., Trends Biotech., 6:299 (1988); Klein, et al., Bio/Tech.,6:559-563 (1988); Sanford, J. C., Physiol Plant, 7:206 (1990); Klein, etal., Biotechnology, 10:268 (1992). See also, U.S. Pat. No. 5,015,580(Christou, et al.), issued May 14, 1991 and U.S. Pat. No. 5,322,783.

Another method for physical delivery of DNA to plants is sonication oftarget cells. Zhang, et al., Bio/Technology, 9:996 (1991).Alternatively, liposome and spheroplast fusion have been used tointroduce expression vectors into plants. Deshayes, et al., EMBO J.,4:2731 (1985); Christou, et al., Proc Natl. Acad. Sci. USA, 84:3962(1987). Direct uptake of DNA into protoplasts using CaCl₂)precipitation, polyvinyl alcohol or poly-L-ornithine have also beenreported. Hain, et al., Mol. Gen. Genet., 199:161 (1985) and Draper, etal., Plant Cell Physiol., 23:451 (1982). Electroporation of protoplastsand whole cells and tissues has also been described (D'Halluin, et al.,Plant Cell, 4:1495-1505 (1992); and Spencer, et al., Plant Mol. Biol.,24:51-61 (1994)).

Following transformation of soybean target tissues, expression of theabove-described selectable marker genes allows for preferentialselection of transformed cells, tissues, and/or plants, usingregeneration and selection methods well known in the art.

The foregoing methods for transformation would typically be used forproducing a transgenic variety. The transgenic variety could then becrossed with another (non-transformed or transformed) variety in orderto produce a new transgenic variety. Alternatively, a genetic trait thathas been engineered into a particular soybean line using the foregoingtransformation techniques could be moved into another line usingtraditional backcrossing techniques that are well known in the plantbreeding arts. For example, a backcrossing approach could be used tomove an engineered trait from a public, non-elite variety into an elitevariety, or from a variety containing a foreign gene in its genome intoa variety or varieties that do not contain that gene. As used herein,“crossing” can refer to a simple x by y cross or the process ofbackcrossing depending on the context.

Likewise, by means of one embodiment, agronomic genes can be expressedin transformed plants. More particularly, plants can be geneticallyengineered to express various phenotypes of agronomic interest.Exemplary genes implicated in this regard include, but are not limitedto, those categorized below:

1. Genes that Confer Resistance to Pests or Disease and that Encode:

A. Plant disease resistance genes. Plant defenses are often activated byspecific interaction between the product of a disease resistance gene(R) in the plant and the product of a corresponding avirulence (Avr)gene in the pathogen. A plant variety can be transformed with one ormore cloned resistance genes to engineer plants that are resistant tospecific pathogen strains. See, for example, Jones, et al., Science,266:789 (1994) (cloning of the tomato Cf-9 gene for resistance toCladosporium fulvum); Martin, et al., Science, 262:1432 (1993) (tomatoPto gene for resistance to Pseudomonas syringae pv. tomato encodes aprotein kinase); Mindrinos, et al., Cell, 78:1089 (1994) (ArabidopsisRSP2 gene for resistance to Pseudomonas syringae); McDowell & Woffenden,Trends Biotechnol., 21(4):178-83 (2003); and Toyoda, et al., TransgenicRes., 11 (6):567-82 (2002).

B. A gene conferring resistance to a pest, such as soybean cystnematode. See, e.g., U.S. Pat. No. 5,994,627.

3. Genes that Confer or Contribute to a Value-Added Trait, Such as:

A. Modified fatty acid metabolism, for example, by transforming a plantwith an antisense gene of stearyl-ACP desaturase to increase stearicacid content of the plant. See, Knultzon, et al., Proc. Natl. Acad. Sci.USA, 89:2625 (1992).

B. Decreased phytate content: 1) Introduction of a phytase-encoding geneenhances breakdown of phytate, adding more free phosphate to thetransformed plant. For example, see, Van Hartingsveldt, et al., Gene,127:87 (1993), for a disclosure of the nucleotide sequence of anAspergillus niger phytase gene. 2) Up-regulation of a gene that reducesphytate content. In maize, this, for example, could be accomplished bycloning and then re-introducing DNA associated with one or more of thealleles, such as the LPA alleles, identified in maize mutantscharacterized by low levels of phytic acid, such as in Raboy, et al.,Maydica, 35:383 (1990), and/or by altering inositol kinase activity asin, for example, U.S. Pat. Nos. 7,425,442, 7,714,187, 6,197,561,6,2191,224, 6,855,869, 6,391,348, 6,197,561, and 6,291,224; U.S. Publ.Nos. 2003/000901, 2003/0009011, and 2006/272046; and International Pub.Nos. WO 98/45448, and WO 01/04147.

C. Modified carbohydrate composition effected, for example, bytransforming plants with a gene coding for an enzyme that alters thebranching pattern of starch, or a gene altering thioredoxin, such as NTRand/or TRX (See, U.S. Pat. No. 6,531,648, which is incorporated byreference for this purpose), and/or a gamma zein knock out or mutant,such as cs27 or TUSC27 or en27 (See, U.S. Pat. Nos. 6,858,778, 7,741,533and U.S. Publ. No. 2005/0160488, which are incorporated by reference forthis purpose). See, Shiroza, et al., J. Bacteriol., 170:810 (1988)(nucleotide sequence of Streptococcus mutans fructosyltransferase gene);Steinmetz, et al., Mol. Gen. Genet., 200:220 (1985) (nucleotide sequenceof Bacillus subtilis levansucrase gene); Pen, et al., Bio/Technology,10:292 (1992) (production of transgenic plants that express Bacilluslicheniformis α-amylase); Elliot, et al., Plant Molec. Biol., 21:515(1993) (nucleotide sequences of tomato invertase genes); Søgaard, etal., J. Biol. Chem., 268:22480-22484 (1993) (site-directed mutagenesisof barley α-amylase gene); Fisher, et al., Plant Physiol., 102:1045(1993) (maize endosperm starch branching enzyme II); International Pub.No. WO 99/10498 (improved digestibility and/or starch extraction throughmodification of UDP-D-xylose 4-epimerase, Fragile 1 and 2, Ref 1, HCHL,C4H); U.S. Pat. No. 6,232,529 (method of producing high oil seed bymodification of starch levels (AGP)). The fatty acid modification genesmentioned above may also be used to affect starch content and/orcomposition through the interrelationship of the starch and oilpathways.

D. Elevated oleic acid via FAD-2 gene modification and/or decreasedlinolenic acid via FAD-3 gene modification. See, U.S. Pat. Nos.5,952,544, 6,063,947, and 6,323,392. Linolenic acid is one of the fivemost abundant fatty acids in soybean seeds. The low oxidative stabilityof linolenic acid is one reason that soybean oil undergoes partialhydrogenation. When partially hydrogenated, all unsaturated fatty acidsform trans fats. Soybeans are the largest source of edible-oils in theU.S. and 40% of soybean oil production is partially hydrogenated. Theconsumption of trans fats increases the risk of heart disease.Regulations banning trans fats have encouraged the development of lowlinolenic soybeans. Soybeans containing low linolenic acid percentagescreate a more stable oil requiring hydrogenation less often. Thisprovides trans fat free alternatives in products such as cooking oil.

E. Altering conjugated linolenic or linoleic acid content, such as inU.S. Pat. No. 6,593,514. Altering LEC1, AGP, Dekl, Superall, milps, andvarious Ipa genes, such as Ipal, Ipa3, hpt, or hggt.

4. Genes that Control Male Sterility:

There are several methods of conferring genetic male sterilityavailable, such as multiple mutant genes at separate locations withinthe genome that confer male sterility, as disclosed in U.S. Pat. Nos.4,654,465 and 4,727,219 to Brar, et al., and chromosomal translocationsas described by Patterson in U.S. Pat. Nos. 3,861,709 and 3,710,511. Inaddition to these methods, Albertsen, et al., U.S. Pat. No. 5,432,068,describes a system of nuclear male sterility which includes: identifyinga gene which is critical to male fertility; silencing this native genewhich is critical to male fertility; removing the native promoter fromthe essential male fertility gene and replacing it with an induciblepromoter; inserting this genetically engineered gene back into theplant; and thus creating a plant that is male sterile because theinducible promoter is not “on” resulting in the male fertility gene notbeing transcribed. Fertility is restored by inducing, or turning “on,”the promoter, which in turn allows the gene that confers male fertilityto be transcribed.

Genetic Marker Profile Through SSR and First Generation Progeny

In addition to phenotypic observations, a plant can also be identifiedby its genotype. The genotype of a plant can be characterized through agenetic marker profile which can identify plants of the same variety, ora related variety, or be used to determine or validate a pedigree.Genetic marker profiles can be obtained by techniques such asRestriction Fragment Length Polymorphisms (RFLPs), Randomly AmplifiedPolymorphic DNAs (RAPDs), Arbitrarily Primed Polymerase Chain Reaction(AP-PCR), DNA Amplification Fingerprinting (DAF), Sequence CharacterizedAmplified Regions (SCARs), Amplified Fragment Length Polymorphisms(AFLPs), Simple Sequence Repeats (SSRs) (which are also referred to asMicrosatellites), and Single Nucleotide Polymorphisms (SNPs). Forexample, see, Cregan, et al., “An Integrated Genetic Linkage Map of theSoybean Genome,” Crop Science, 39:1464-1490 (1999) and Berry, et al.,“Assessing Probability of Ancestry Using Simple Sequence RepeatProfiles: Applications to Maize Inbred Lines and Soybean Varieties,”Genetics, 165:331-342 (2003), each of which are incorporated byreference herein in their entirety.

Particular markers used for these purposes are not limited to anyparticular set of markers, but are envisioned to include any type ofmarker and marker profile which provides a means of distinguishingvarieties. One method of comparison is to use only homozygous loci forsoybean cultivar 2940889.

Primers and PCR protocols for assaying these and other markers aredisclosed in the Soybase (sponsored by the USDA Agricultural ResearchService and Iowa State University). In addition to being used foridentification of soybean variety 2940889, and plant parts and plantcells of soybean variety 2940889, the genetic profile may be used toidentify a soybean plant produced through the use of soybean cultivar2940889 or to verify a pedigree for progeny plants produced through theuse of soybean cultivar 2940889. The genetic marker profile is alsouseful in breeding and developing backcross conversions.

One embodiment comprises a soybean plant characterized by molecular andphysiological data obtained from the sample of said variety depositedwith a Budapest Depository. Further provided by the embodiment(s) is asoybean plant formed by the combination of the disclosed soybean plantor plant cell with another soybean plant or cell and comprising thehomozygous alleles of the variety. “Cell” as used herein includes aplant cell, whether isolated, in tissue culture or incorporated in aplant or plant part.

Means of performing genetic marker profiles using SSR polymorphisms arewell known in the art. SSRs are genetic markers based on polymorphismsin repeated nucleotide sequences, such as microsatellites. A markersystem based on SSRs can be highly informative in linkage analysisrelative to other marker systems in that multiple alleles may be present(“linkage” refers to a phenomenon wherein alleles on the same chromosometend to segregate together more often than expected by chance if theirtransmission was independent). Another advantage of this type of markeris that, through use of flanking primers, detection of SSRs can beachieved, for example, by the polymerase chain reaction (PCR), therebyeliminating the need for labor-intensive Southern hybridization. The PCRdetection is done by use of two oligonucleotide primers flanking thepolymorphic segment of repetitive DNA. Repeated cycles of heatdenaturation of the DNA followed by annealing of the primers to theircomplementary sequences at low temperatures, and extension of theannealed primers with DNA polymerase, comprise the major part of themethodology.

Following amplification, markers can be scored by electrophoresis of theamplification products. Scoring of marker genotype is based on the sizeof the amplified fragment, which may be measured by the number of basepairs of the fragment. While variation in the primer used or inlaboratory procedures can affect the reported fragment size, relativevalues should remain constant regardless of the specific primer orlaboratory used. When comparing varieties, it is preferable if all SSRprofiles are performed in the same lab.

Primers used are publicly available and may be found in the Soybase orCregan supra. See also, U.S. application Ser. No. 09/581,970 (NucleotidePolymorphisms in Soybean); U.S. Pat. No. 6,162,967 (Positional Cloningof Soybean Cyst Nematode Resistance Genes); and U.S. Pat. No. 7,288,386(Soybean Sudden Death Syndrome Resistant Soybeans and Methods ofBreeding and Identifying Resistant Plants), the disclosure of which areincorporated herein by reference.

The SSR profile of soybean plant 2940889 can be used to identify plantscomprising soybean cultivar 2940889 as a parent, since such plants willcomprise the same homozygous alleles as soybean cultivar 2940889.Because the soybean variety is essentially homozygous at all relevantloci, most loci should have only one type of allele present. Incontrast, a genetic marker profile of an F₁ progeny should be the sum ofthose parents, e.g., if one parent was homozygous for allele x at aparticular locus, and the other parent homozygous for allele y at thatlocus, then the F₁ progeny will be xy (heterozygous) at that locus.Subsequent generations of progeny produced by selection and breeding areexpected to be of genotype x (homozygous), y (homozygous), or xy(heterozygous) for that locus position. When the F₁ plant is selfed orsibbed for successive filial generations, the locus should be either xor y for that position.

In addition, plants and plant parts substantially benefiting from theuse of soybean cultivar 2940889 in their development, such as soybeancultivar 2940889 comprising a backcross conversion, transgene, orgenetic sterility factor, may be identified by having a molecular markerprofile with a high percent identity to soybean cultivar 2940889. Such apercent identity might be 95%, 96%, 97%, 98%, 99%, 99.5%, or 99.9%identical to soybean cultivar 2940889. Percent identity refers to thecomparison of the homozygous alleles of two soybean varieties. Percentidentity or percent similarity is determined by comparing astatistically significant number of the homozygous alleles of twodeveloped varieties. For example, a percent identity of 90% betweensoybean variety 1 and soybean variety 2 means that the two varietieshave the same allele at 90% of their loci.

The SSR profile of soybean cultivar 2940889 can also be used to identifyessentially derived varieties and other progeny varieties developed fromthe use of soybean cultivar 2940889, as well as cells and other plantparts thereof. Such plants may be developed using the markers, forexample, identified in U.S. Pat. Nos. 6,162,967, and 7,288,386. Progenyplants and plant parts produced using soybean cultivar 2940889 may beidentified by having a molecular marker profile of at least 25%, 30%,35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 76%, 77%, 78%, 79%, 80%,81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%,95%, 96%, 97%, 98%, 99%, or 99.5% genetic contribution from soybeanvariety, as measured by either percent identity or percent similarity.Such progeny may be further characterized as being within a pedigreedistance of soybean cultivar 2940889, such as within 1, 2, 3, 4, or 5 orless cross-pollinations to a soybean plant other than soybean cultivar2940889 or a plant that has soybean cultivar 2940889 as a progenitor.Unique molecular profiles may be identified with other molecular toolssuch as SNPs and RFLPs.

While determining the SSR genetic marker profile of the plants describedsupra, several unique SSR profiles may also be identified which did notappear in either parent of such plant. Such unique SSR profiles mayarise during the breeding process from recombination or mutation. Acombination of several unique alleles provides a means of identifying aplant variety, an F₁ progeny produced from such variety, and progenyproduced from such variety.

Tissue Culture

Further reproduction of the variety can occur by tissue culture andregeneration. Tissue culture of various tissues of soybeans andregeneration of plants therefrom is well-known and widely published. Forexample, reference may be had to Komatsuda, T., et al., Crop Sci.,31:333-337 (1991); Stephens, P. A., et al., Theor. Appl. Genet.,82:633-635 (1991); Komatsuda, T., et al., Plant Cell, Tissue and OrganCulture, 28:103-113 (1992); Dhir, S., et al., Plant Cell Reports,11:285-289 (1992); Pandey, P., et al., Japan J. Breed., 42:1-5 (1992);and Shetty, K., et al., Plant Science, 81:245-251 (1992); as well asU.S. Pat. Nos. 5,024,944 and 5,008,200. Thus, another aspect orembodiment is to provide cells which upon growth and differentiationproduce soybean plants having the physiological and morphologicalcharacteristics of soybean cultivar 2940889.

Regeneration refers to the development of a plant from tissue culture.The term “tissue culture” indicates a composition comprising isolatedcells of the same or a different type or a collection of such cellsorganized into parts of a plant. Exemplary types of tissue cultures areprotoplasts, calli, plant clumps, and plant cells that can generatetissue culture that are intact in plants or parts of plants, such asembryos, pollen, flowers, seeds, pods, petioles, leaves, stems, roots,root tips, anthers, pistils, and the like. Means for preparing andmaintaining plant tissue culture are well known in the art. By way ofexample, a tissue culture comprising organs has been used to produceregenerated plants. U.S. Pat. Nos. 5,959,185, 5,973,234, and 5,977,445describe certain techniques, the disclosures of which are incorporatedherein by reference.

Plant Products

The seed of soybean cultivar 2940889, the plant produced from the seed,the hybrid soybean plant produced from the crossing of the variety withany other soybean plant, hybrid seed, and various parts of the hybridsoybean plant can be utilized for plant products. Industrial usesinclude but are not limiting to, human food, livestock feed, and as araw material in industry.

As used herein the term plant product will be understood to mean theproduct derived from or produced by a plant of soybean cultivar 2940889,for example, the tissues or structures of the plant of soybean cultivar2940889 such as the flower, fruit, seed, grain, leaves, stems etc.,produced by the plant. Further, the soybean seeds produced from orderived from soybean cultivar 2940889 can be crushed, or a component ofthe soybean seeds can be extracted, in order to comprise a plantproduct, such as protein concentrate, protein isolate, soybean hulls,meal, flour, or oil for a food or feed product.

The soybean is the world's leading source of vegetable oil and proteinmeal. The oil extracted from soybeans is used for cooking oil,margarine, and salad dressings. Soybean oil is composed of saturated,monounsaturated, and polyunsaturated fatty acids. It has a typicalcomposition of 11% palmitic, 4% stearic, 25% oleic, 50% linoleic, and 9%linolenic fatty acid content (“Economic Implications of Modified SoybeanTraits Summary Report,” Iowa Soybean Promotion Board and AmericanSoybean Association Special Report 92S (May 1990)). Changes in fattyacid composition for improved oxidative stability and nutrition areconstantly sought after. Industrial uses of soybean oil, which issubjected to further processing, include ingredients for paints,plastics, fibers, detergents, cosmetics, lubricants, and biodiesel fuel.Soybean oil may be split, inter-esterified, sulfurized, epoxidized,polymerized, ethoxylated, or cleaved. Designing and producing soybeanoil derivatives with improved functionality and improved oliochemistryis a rapidly growing field. The typical mixture of triglycerides isusually split and separated into pure fatty acids, which are thencombined with petroleum-derived alcohols or acids, nitrogen, sulfonates,chlorine, or with fatty alcohols derived from fats and oils to producethe desired type of oil or fat.

Soybean cultivar 2940889 can be used to produce soybean oil. To producesoybean oil, the soybeans harvested from soybean cultivar 2940889 arecracked, adjusted for moisture content, rolled into flakes and the oilis solvent-extracted from the flakes with commercial hexane. The oil isthen refined, blended for different applications, and sometimeshydrogenated. Soybean oils, both liquid and partially hydrogenated, areused domestically and exported, sold as “vegetable oil” or are used in awide variety of processed foods.

Soybeans are also used as a food source for both animals and humans.Soybeans are widely used as a source of protein for poultry, swine, andcattle feed. During processing of whole soybeans, the fibrous hull isremoved and the oil is extracted. The remaining soybean meal is acombination of carbohydrates and approximately 50% protein.

Soybean cultivar 2940889 can be used to produce meal. After oil isextracted from whole soybeans harvested from soybean cultivar 2940889,the remaining material or “meal” is “toasted” (a misnomer because theheat treatment is with moist steam) and ground in a hammer mill. Soybeanmeal is an essential element of the American production method ofgrowing farm animals, such as poultry and swine, on an industrial scalethat began in the 1930s; and more recently the aquaculture of catfish.Ninety-eight percent of the U.S. soybean crop is used for livestockfeed. Soybean meal is also used in lower end dog foods. Soybean mealproduced from soybean cultivar 2940889 can also be used to producesoybean protein concentrate and soybean protein isolate.

In addition to soybean meal, soybean cultivar 2940889 can be used toproduce soy flour. Soy flour refers to defatted soybeans where specialcare was taken during desolventizing (not toasted) to minimizedenaturation of the protein and to retain a high Nitrogen SolubilityIndex (NSI) in making the flour. Soy flour is the starting material forproduction of soy concentrate and soy protein isolate. Defatted soyflour is obtained from solvent extracted flakes, and contains less than1% oil. Full-fat soy flour is made from unextracted, dehulled beans, andcontains about 18% to 20% oil. Due to its high oil content, aspecialized Alpine Fine Impact Mill must be used for grinding ratherthan the more common hammer mill. Low-fat soy flour is made by addingback some oil to defatted soy flour. The lipid content varies accordingto specifications, usually between 4.5% and 9%. High-fat soy flour canalso be produced by adding back soybean oil to defatted flour at thelevel of 15%. Lecithinated soy flour is made by adding soybean lecithinto defatted, low-fat or high-fat soy flours to increase theirdispersibility and impart emulsifying properties. The lecithin contentvaries up to 15%.

For human consumption, soybean cultivar 2940889 can be used to produceedible protein ingredients which offer a healthier, less expensivereplacement for animal protein in meats, as well as in dairy-typeproducts. The soybeans produced by soybean cultivar 2940889 can beprocessed to produce a texture and appearance similar to many otherfoods. For example, soybeans are the primary ingredient in many dairyproduct substitutes (e.g., soy milk, margarine, soy ice cream, soyyogurt, soy cheese, and soy cream cheese) and meat substitutes (e.g.,veggie burgers). These substitutes are readily available in mostsupermarkets. Although soy milk does not naturally contain significantamounts of digestible calcium (the high calcium content of soybeans isbound to the insoluble constituents and remains in the soy pulp), manymanufacturers of soy milk sell calcium-enriched products as well. Soy isalso used in tempe, where the beans (sometimes mixed with grain) arefermented into a solid cake.

Additionally, soybean cultivar 2940889 can be used to produce varioustypes of “fillers” in meat and poultry products. Food service, retail,and institutional (primarily school lunch and correctional) facilitiesregularly use such “extended” products, that is, products which containsoy fillers. Extension may result in diminished flavor, but fat andcholesterol are reduced by adding soy fillers to certain products.Vitamin and mineral fortification can be used to make soy productsnutritionally equivalent to animal protein; the protein quality isalready roughly equivalent.

Agricultural Treatment Agents

A plant, or its environment, can be contacted with a wide variety of“agriculture treatment agents.” As used herein, an “agriculturetreatment agent”, or “treatment agent”, or “agent” can refer to anyexogenously provided compound that can be brought into contact with aplant tissue (e.g. a seed) or its environment that affects a plant'sgrowth, development and/or performance, including agents that affectother organisms in the plant's environment when those effectssubsequently alter a plant's performance, growth, and/or development(e.g. an insecticide that kills plant pathogens in the plant'senvironment, thereby improving the ability of the plant to tolerate theinsect's presence). Agriculture treatment agents also include a broadrange of chemicals and/or biological substances that are applied toseeds, in which case they are commonly referred to as seed treatmentsand/or seed dressings.
